Fuel Injection Pump Working Principle - Animation Apr 2026

: Uses a single pumping element and a rotor to distribute fuel to all cylinders in sequence, typically found in smaller vehicles.

: As the plunger reaches the bottom of its stroke, fuel from the supply tank floods the barrel through inlet ports . Fuel Injection pump working principle - Animation

: When the pressure is high enough to overcome the spring force of the delivery valve , it snaps open, sending a high-pressure pulse of fuel through the lines to the injectors. : Uses a single pumping element and a

: In modern systems, an Electronic Control Unit (ECU) uses signals to trigger high-pressure solenoid valves , replacing the mechanical rack and governor for more precise control. : In modern systems, an Electronic Control Unit

: When you press the accelerator, a control rack rotates the plunger. This changes the position of the helix, determining how long the spill port stays covered and, consequently, how much fuel is delivered to the cylinder. Common Pump Types in Animations
